Faux Pause 2: Warmest November on Record, Reports NASA, as New Studies Confirm Warming Trend - by Joe Romm

Now two new studies demolish the myth that warming — including surface warming — has not continued apace.  Stefan Rahmstorf, Co-Chair of Earth System Analysis at the Potsdam Institute for Climate Impact Research, discusses the first paper at RealClimate:

A new study by British and Canadian researchers shows that the global temperature rise of the past 15 years has been greatly underestimated.  The reason is the data gaps in the weather station network, especially in the Arctic.  If you fill these data gaps using satellite measurements, the warming trend is more than doubled in the widely used HadCRUT4 data, and the much-discussed “warming pause” has virtually disappeared.

“There are no permanent weather stations in the Arctic Ocean, the place on Earth that has been warming fastest,” as New Scientist explained five years ago.  “The UK’s Hadley Centre record simply excludes this area, whereas the NASA version assumes its surface temperature is the same as that of the nearest land-based stations.”
